Painted or Plated? Options

[dereknlee]

I'm trying to determine what parts were originally plated and which parts were painted. The parts vault has been very helpful so far, but I couldn't find what I was after for these parts in particular. I'd like to update the parts vault with the determinations from this thread.

So was this part painted or plated? If plated, was it bright silver (blue) or yellow chromate? Or maybe the answer is neither and it was black oxide or another type of finish?

Right now I am rebuilding the suspension so all my questions revolve around those parts:

91434103300 Change Lever


I suspect plated with yellow chromate, because of this photo here.

91134111500 Adjusting Screw
This threads into the change lever shown above. My guess is black oxide.

91433153303 Intermediate Layer (shim)



99908402902 M14x1.5 locking nuts for the trailing arm pivots (the ones with the weird slit).

That's all for now. Thanks,

I think many of those parts were black oxide. However, OE parts are generally well rusted, and hard to determine original state. Replacement parts were often not the same as the OE parts. The OE parts were generally lowest possible cost, while replacement parts had a healthy profit margin.
